What it measures: How tangled the control flow is — methods with many branches are hard to test and change.

Method: Cyclomatic complexity per method (1 + decision points), computed exhaustively across production source; test projects separated by convention. Deterministic.

Maturity: Documented → Verified → Prevented · effective 4.0 / 10 · rule-coverage 100% · ceiling Prevented

184 method(s) exceeded the cyclomatic complexity threshold of 15; the worst was useAutocomplete.useAutocomplete at 327. A further 1 method(s) were over the threshold but excluded as flat dispatchers (a long switch/match over independent cases: many branches, almost no nesting), the largest being parseMarkdown.createRender at 28 — they are counted neither in the figure above nor in this dimension's score. 1 file carries no cyclomatic complexity row at all for this reason — every one of its over-threshold methods was excluded, so the exclusion is disclosed nowhere in the file itself: packages-internal/markdown/parseMarkdown.mjs (parseMarkdown.createRender at 28). They are named here because the per-file figures other dimensions report are taken BEFORE this exclusion, so such a file can show a high maximum complexity elsewhere in this report and nothing here, with nothing to reconcile the two.

Its 309 `devDependencies` declaration(s) are excluded: a consumer installs none of them. ★ DEPTH: this is the DIRECT production set the lockfile resolves, NOT the transitive closure — only one of the four lock dialects this pass reads states a full graph, so a banned licence pulled in only by a dependency's OWN dependencies is outside this verdict, exactly as the JVM arm's declaration-site verdict is. ★ Each licence is the one the registry publishes for the package's CURRENT release rather than for the pinned version, which is the same caveat the Hex and RubyGems arms carry. 4 of them publish no licence this pass can read on registry.npmjs.org — an absent field, `UNLICENSED`, or a `SEE LICENSE IN <file>` pointer into a tarball this pass does not download; that is missing data, not a violation, and none of them is charged.

Method: Polyglot static analysis via semgrep across the repo using the pinned, image-baked p/security-audit + p/owasp-top-ten rulesets (no scan-time registry fetch); severity rules (ERROR/WARNING/INFO) map to a full-band severity-weighted score. Exhaustive, deterministic; degrades on parse failure.

Fix the syntax error (or exclude the file deliberately) and re-scan to cover them. Separately, one or more rules could not re-parse an embedded snippet in 1 file(s) (e.g. a workflow `run:` block read as shell).

Method: Dependency-CVE scan across every ecosystem the repository declares, scored ONCE. Three sources are unioned and deduplicated by advisory identity (rule id + alias closure, CVE<->GHSA) scoped to package+version, keeping the worst severity: `osv-scanner --recursive` over osv.dev for Dart pub, Elixir/Hex, Go, Java and Kotlin via Maven/Gradle, npm, PHP/Composer, Python/PyPI, RubyGems, Rust/Cargo and Swift; `trivy fs --scanners vuln` for npm lockfiles; and `dotnet list package --vulnerable --include-transitive` for NuGet (with per-advisory collapse of the project x target-framework fan-out), plus a DECLARED-dependency arm that resolves a published gem's gemspec against rubygems.org where no Gemfile.lock is committed. `SeverityScore(c,h,m,l, normalizer 8.0)`.

What it measures: Whether files that change together actually belong together — pairs that repeatedly co-change in git history despite having no explicit code dependency, surfacing the hidden/logical coupling (and boundaries in the wrong place) a static scan can't see.

Method: Pairwise co-occurrence over the per-commit file sets in git history (production source only — tests and generated dropped): Degree-of-Coupling = shared ÷ min individual revisions, reported above noise floors (each file ≥10 revisions, ≥5 shared commits, ≥50% strength); sweeping commits excluded. Deterministic over fixed history.

Coverage: Population: PRODUCTION source files only — test and generated files are dropped before pairing, so a class co-changing with its own test (trivially ~100%) can't drown the real production↔production coupling. Pairs ranked by Degree-of-Coupling. A non-source file is never a coupling PARTICIPANT either: documentation, schemas, config and data files are dropped with the rest, so a code↔docs pair — a command and the reference page that restates it — is not reported however strongly the two co-change; nor is coupling that runs THROUGH a build step or config file.

What it measures: Whether any dependency the repository declares is published as MALICIOUS rather than merely vulnerable — a package that is an attacker's work, in any ecosystem osv-scanner reads. Scored apart from D30 because the answer is binary: there is no safe version to upgrade to, and the fix is to remove the package and rotate every credential it could have read.

Method: The same dependency scan D30 reads, partitioned on the scanner's own classification rather than rescanned: a row is MALICIOUS when its id is in the `MAL-` space (the ossf/malicious-packages feed) OR its `database_specific.cwe_ids` carries `CWE-506` ("Embedded Malicious Code"). Both channels are structural; the summary text is deliberately NOT read, because a malicious-package record whose summary says only "Critical severity vulnerability" is a real shape ([GHSA redacted]) and a text matcher misses it. Scored BINARY: any surviving row is 0, whatever its severity and however many CVEs sit beside it — a hostile dependency is not a quantity. Applicability and degradation are D30's: NotApplicable only when no ecosystem is readable, and an unscannable ecosystem degrades rather than reading clean. SCORED, not informational.

What it measures: Whether anyone still ships security patches for the platform this repository RUNS ON — the runtime it pins and the framework majors its own constraints hold it to. Separate from D12 because the question differs: a current Django on an end-of-life Python is perfectly up to date and completely unsupported, and the fix is a migration rather than a version bump. What the repository says it merely SUPPORTS is never charged.

Method: End-of-life PLATFORM read from the repository's own declarations and graded against a FROZEN, dated table of vendor support dates — no network, no feed, no API, so this dimension answers identically inside a closed scan fence. Two subjects: a RUNTIME the project pins (a single or all-end-of-life TargetFramework, a .nvmrc or .python-version, a requires-python CAP) and a FRAMEWORK major a dependency constraint cannot move off (a caret, tilde or exact version; `vue@^2.7.16` pins Vue 2). A FLOOR is deliberately never charged — `requires-python = ">=3.8"` states what a package SUPPORTS, not what it runs on — and a multi-target project is charged only when EVERY target is out of support. Runtime 4.0/product capped 8.0, framework 1.5 capped 4.5. The table is safe to freeze because a statement about support that ended in the past cannot become false: it loses recall as it ages, never precision, and a test asserts every entry predates the freeze date. Disjoint from D31 (a container image's OS layer) and D29 (the toolchain a CI workflow installs). Abstains when the repository declares no platform this pass reads — never scores it clean.

A FLOOR is deliberately never charged: `requires-python = ">=3.8"` states what the package SUPPORTS, not what it runs on, and a well-maintained library declares exactly that while running its own CI on a current release. The end-of-life facts are FROZEN and dated, so this dimension needs no network and answers identically inside a closed scan fence; as the table ages it loses recall and never precision, because a statement about support that ended in the past cannot become false. The OS layer of a container image is D31's question and the toolchain a CI workflow installs is D29's; this row is neither.

✓ On the Gold path — maintain.

Other · Accessibility — Whether non-text content carries a text alternative — img/area/input[type=image] have alt, a meaningful svg has a title or aria-label, video has a captions track, and object/embed/canvas have a name or fallback content. Static markup readiness, not a WCAG conformance claim.

Method: Static markup-model scan: every img/area/input[type=image] checked for alt, svg[role=img] for a title/aria-label, video for a captions <track>. Components skipped, spreads suppressed. Deterministic, hard fact per element.

Coverage: Population: image/media elements — img, area, input[type=image], svg, video, object, embed, canvas — across the PARSED MARKUP files only (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx); components, hidden subtrees and dynamic-attribute elements are skipped. Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is NOT read by any producer, so it contributes no element to this population; where such a frontend is present the card discloses it as an analyzer gap rather than scoring around it.

Other · Accessibility — Whether form controls have a programmatic label (an associated label, aria-label or aria-labelledby), buttons have text, links have an accessible name, a click handler on a plain element names the control it declares, fieldsets have a non-empty legend, known UI-library field components carry a label prop, and a placeholder isn't used as the only label. Static markup readiness, not a WCAG conformance claim.

Method: Static markup-model scan: inputs/selects/textareas checked for an associated label[for]/wrapping label/aria-label/aria-labelledby (per document), buttons for accessible text, fieldsets for a legend; placeholder-only labelling flagged. Deterministic, hard fact per control.

Coverage: Population: form controls, buttons, links, fieldsets and known UI-library field components in the PARSED MARKUP files only (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx); components, hidden subtrees and spread/dynamic-attribute elements are skipped, so a control whose label arrives through a spread or a runtime expression is deliberately not judged. Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

• This UI-library field component has no label / aria-label / aria-labelledby / id / name — and neither does anything it renders — so it likely renders an unlabelled control. Name it whichever way this library supports: a label prop, an aria-label, or an id on the rendered control with a <label htmlFor> pointing at it. For a group of controls, name the group itself (aria-label, or a fieldset with a legend) — labelling each item leaves the set unnamed. (×35) — docs/data/material/components/autocomplete/Asynchronous.tsx:41, docs/data/material/components/autocomplete/ComboBox.tsx:7, docs/data/material/components/autocomplete/CustomSingleValueRendering.tsx:9, …
• This UI-library field component has no label / aria-label / aria-labelledby / id / name, and nothing it renders carries one either. The text inside it does not stand in for one: these compound APIs render a trigger with role="combobox" (or role="button"), and those roles take their name from the AUTHOR, not from their content — so the words on screen never reach the accessibility tree as a name. Name it whichever way this library supports: a label prop, an aria-label, or an id on the rendered control with a <label htmlFor> pointing at it. For a group of controls, name the group itself (aria-label, or a fieldset with a legend) — labelling each item leaves the set unnamed. (×4) — docs/data/material/customization/css-theme-variables/DisableTransitionOnChange.tsx:22, docs/src/components/productX/XGridFullDemo.tsx:86, docs/src/components/productX/XGridFullDemo.tsx:93, …
• This control has no associated label. Add a <label htmlFor> / wrapping <label> / aria-label / aria-labelledby so assistive tech can name it. — docs/data/system/getting-started/the-sx-prop/DynamicValues.tsx:17

What to do

• Give every control a programmatic label (a <label for> / wrapping <label> / aria-label) and every button text — a placeholder is not a label.

Other · Accessibility — Whether pages declare a language (well-formed BCP-47) and a non-empty title, expose exactly one main landmark and a sane heading order with non-empty headings, keep zoom enabled, title their iframes, give data tables header cells, and avoid meta-refresh. Static markup readiness, not a WCAG conformance claim.

Method: Static markup-model scan: html lang, document <title>, a main landmark and heading order on full documents only, plus zoom-disabling viewports, untitled iframes and meta-refresh anywhere. Deterministic, per structural checkpoint.

Coverage: Population: the PARSED MARKUP documents (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx). The page-level checks — lang, title, single main landmark — fire ONCE PER FULL DOCUMENT (an <html> root) and never on a partial or component fragment, so a repo of fragments is assessed only on the per-element checks (heading order, table headers, iframe titles, meta-refresh, zoom). Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

Other · Accessibility — Whether interactive behaviour is keyboard-reachable — no click handler on a non-interactive element lacking a role, tabindex and key handler, no element the repo's own CSS styles `cursor: pointer` without giving it any of the three, no unfocusable element whose only binding is a mouse enter/leave pair or a double-click, no positive tabindex, no href-less anchor, no placeholder-href (#/javascript) link acting as a button. Static markup readiness, not a WCAG conformance claim.

Method: Static markup-model scan: click handlers on non-interactive elements lacking role+tabindex+key handler, positive tabindex values, and href-less anchors. Components skipped, spreads suppressed. Deterministic, hard fact per element.

Coverage: Population: interactive elements plus elements the markup gives a click/key handler or the repo's own CSS styles `cursor: pointer`, in the PARSED MARKUP files only (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx). Keyboard reachability is judged from the markup, never from a rendered page. ★ An interactive element declared in a tagged-template (html`…`) or hyperscript frontend is NOT in this population — no producer reads either — so an empty population is reported as an analyzer gap, never as "this repository has no interactive elements".

Other · Accessibility — Whether ARIA is used correctly — valid non-abstract roles, the ARIA state a role requires, valid (non-misspelled) aria-* attribute names, in-enum values for token-typed aria-* attributes, and no aria-hidden on (or wrapping) a focusable element. Static markup readiness, not a WCAG conformance claim.

Method: Static markup-model scan: role values checked against the WAI-ARIA role set (abstract/invalid flagged), required ARIA state for a role, and aria-hidden on a focusable element. Deterministic, role/attribute level.

Coverage: Population: elements in the PARSED MARKUP files (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx) that carry a role or an aria-* attribute; roles and token values are checked against the ARIA enums exhaustively within that set. An expression-valued (dynamic) role or aria-* value is skipped rather than guessed, and markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

Other · Accessibility — Whether focus outlines aren't removed without a replacement, motion respects prefers-reduced-motion, and literal CSS colour pairs meet contrast — PARTIAL: inline styles, in-repo <style> blocks, in-repo .css files, var() tokens, Tailwind neutral utilities and CSS-in-JS literals are read (hex/rgb/hsl/named), never computed/runtime/external-CDN colour. Static markup readiness, not a WCAG conformance claim.

Method: Static markup/CSS scan: inline outline:none/0, literal inline colour/background contrast against the 4.5:1 AA floor, and <style>-block animation without a prefers-reduced-motion guard. Deterministic but PARTIAL — only inline styles and in-repo CSS literals are visible.

Coverage: Population: styled elements in the PARSED MARKUP files (.html/.htm/.cshtml/.razor/.vue/.svelte/.jsx/.tsx), plus in-repo <style> blocks, in-repo .css files and CSS-in-JS literals. Colour contrast is computed from LITERAL colour pairs only (hex/rgb/hsl/named, including var() tokens and Tailwind neutral utilities) — computed, runtime-themed and external-CDN colour is never resolved, so this is a partial read of contrast by construction. Markup built in script — tagged-template (html`…`) UIs and hyperscript DOM factories — is not read at all.

Other · Accessibility — Whether accessibility is ENFORCED in the toolchain — an accessibility checker configured over the markup (an a11y lint rule set, e.g. eslint-plugin-jsx-a11y or vuejs-accessibility where the project lints JavaScript) and an automated accessibility assertion wired into tests or CI (axe/pa11y/Lighthouse or an equivalent) — on the Documented→Verified→Prevented ladder.

Method: Repo config/CI scan: an accessibility checker configured over the markup (an a11y lint rule set such as eslint-plugin-jsx-a11y / vuejs-accessibility where JavaScript is linted) and an automated accessibility assertion in tests or CI (axe/pa11y/Lighthouse or equivalent), graded on the Documented→Verified→Prevented rungs. Deterministic, presence/rung detection.

Coverage: Population: the repository's own tooling configuration — lint config, test and CI files — NOT the markup. It is read for a configured accessibility checker and an automated accessibility assertion (axe/pa11y/Lighthouse, or a native-toolkit equivalent), and it credits an INVOCATION, never a mention: a licence filename, an import comment or a doc reference earns no rung. Enforcement configured entirely outside the repository leaves no evidence here and cannot be credited.

• Accessibility checks run in tests (Verified) but aren't gated in CI — run the suite that holds those checks in your pipeline so an accessibility regression blocks the merge (Prevented). What was searched, so you can tell an absence from a miss: the 1149 markup file(s) this pass actually assessed, the linter configuration checked in beside them, and this repository's test and CI files — matched by name against the accessibility checkers this dimension carries. An audit run outside the repository, a hosted scanner, or a check whose name is not one of those, is not seen here.

What to do

• Enforce accessibility in the toolchain: add eslint-plugin-jsx-a11y, then run the suite that already asserts accessibility in CI so a regression blocks the merge.

Other · Architecture — How the codebase splits by code ROLE — domain, application, infrastructure, test, generated. The significance map behind the knowledge/coupling weighting, and a DDD signal in its own right: a thin domain core under fat infrastructure is the anemic-domain smell, quantified. How each file's role is decided, because the split is only as good as that: a generated name or a build-output tree makes it Generated, a test project makes it Test, and otherwise the file's NAMESPACE and PATH words are matched against fixed vocabularies in a fixed ORDER — domain, then infrastructure, then application — so a file whose words hit two layers is counted under the earlier one. A production file matching none of them counts as application, so that share reads 'application or unclassified' rather than a measured application layer. Roles come from naming convention, never from what the code does. On this repository the split was taken from the source tree on disk rather than from a loaded .NET workspace, so a file's role is decided by its PATH segments alone — no declared namespace was available to add to the evidence — and generated output is excluded from the census entirely rather than counted as a generated share.

Method: Roslyn line-count by code ROLE: every source file classified Domain/Application/Infrastructure/Test/Generated by namespace + path convention (the shared CodeRoleClassifier), then significant lines summed per role. Deterministic; the advisory score is the business-logic (domain+application) share of production code.

Coverage: Population: ALL source files, each bucketed into ONE of five roles (Domain/Application/Infrastructure/Test/Generated) by namespace + path convention — a file whose layer isn't named in the convention falls to Application (the neutral default), and the split is line-count, not semantic depth or business value.

What to do

• The domain core is a small share of production code, but most of the rest matched no layer vocabulary at all — so this is not yet an anemic-domain finding. The namespace/path convention could not place that code, which makes the composition above a statement about the naming, not about the design. Name the layers (or check that the repository's conventions differ from the ones this check knows) before reading a thin domain into it.

Other · Architecture — Whether the codebase has a recognisable, scale-appropriate structure (a named architectural style, or modular enough for its size) rather than being an ad-hoc ball of mud.

Method: Roslyn plus csproj analysis: architecture style detection (DDD, clean, vertical-slice, CQRS) and structure fitness for repo size. Deterministic.

Maturity · Maturity — Whether the repo and its projects have a README, and whether it's substantive and current.

Method: Filesystem scan: README presence, word count, and headings for depth; git history for staleness. Exhaustive across root and project dirs, deterministic.

What to do

• Add a build/run (quick start) section to the root README — the first thing a newcomer needs.
• Add a 'Testing' section to the root README — how to run the test suite.
• Add an 'Architecture' / 'How it works' section to the root README — the high-level shape.
• Add a README to the 2 of 39 project(s) that lack one — worth up to 0.1 pts.

Maturity · Maturity — Whether key decisions (ADRs) and the high-level shape (C4/diagrams) are written down.

Method: Filesystem scan: ADR folder/naming conventions or content, plus Mermaid/PlantUML/C4/architecture.md discovery. Exhaustive, deterministic.

• No Architecture Decision Records found — no conventional ADR directory, no numbered `NNNN-title` documents in any markup this check reads, and nothing ADR-shaped by content. Design rationale recorded elsewhere (a design-notes tree, a mailing list, pull-request discussion) is not visible to this check and is not re-findable per decision, so a future maintainer cannot ask why one choice was made and get an answer.

What to do

• Record significant decisions one document per decision — dated, stating the context, the decision and its consequences — and keep them together wherever your design docs already live (a conventional `docs/adr/` tree, with each file named `NNNN-title` in whatever markup those docs already use, is the most discoverable form).

Maturity · Maturity — Whether the repo is organised deliberately — src/test separation and consistent project naming.

Method: Filesystem scan: src/test folder separation and namespace-prefix consistency (majority RootNamespace agreement). Exhaustive across projects, deterministic.

Maturity · Maturity — Whether the README actually describes the code that exists (LLM-judged, advisory).

Method: Judged by language model at low temperature: README accuracy versus actual projects, within a disclosed tolerance. Advisory, not a measured number.

Readiness · Readiness — Whether an automated pipeline builds and tests every change.

Method: Filesystem scan: CI workflow files (.github/workflows, .gitlab-ci.yml, etc.) for build and test stages. Exhaustive, deterministic.

Readiness · Readiness — Whether SAST, secret/dependency scanning and performance benchmarking are wired in (presence, not runtime).

Method: Filesystem scan: SAST configuration, dependency-update automation, secret scanning, and a benchmark harness or benchmark step — in this repository's own ecosystem. Exhaustive, deterministic.

• `codeql.yml`, `scorecards.yml` run(s) a static-analysis scan, but no workflow that runs one is triggered by a pull request (or a merge queue, or an unfiltered push) — the scan fires on a schedule or a manual dispatch only. A vulnerable change therefore merges clean and is reported on the next scheduled run, by which time it is on the default branch and the only remedy is a follow-up fix. Add the pull-request trigger to the workflow that runs the scan so the finding arrives before the merge rather than after it.

What to do

• Trigger your SAST workflow on pull requests — a scan that only runs on a cron reports history, it does not gate.
• Add gitleaks/trufflehog in CI to block PRs that introduce committed secrets.

Readiness · Readiness — Whether releases are automated and safely reversible (probes, rolling updates, approval gates) — from manifests/pipeline files, not the live environment.

Method: Filesystem scan: deployment manifests/IaC (K8s YAML, Helm, Terraform) for rolling updates, probes, approval gates, migration hooks. Exhaustive, deterministic.

Readiness · Readiness — Whether releases are traceable — a maintained changelog and explicit version stamping.

Method: Filesystem scan: changelog file presence and version tags in csproj or git tags. Exhaustive, deterministic.

React / JS · Code Health — How much of the frontend is typed TypeScript vs untyped JavaScript.

Method: Frontend file inventory: the share of typed TypeScript vs untyped JavaScript across the source tree. Deterministic, exhaustive over frontend files.

• 1262 typed · 1348 plain JS — the untyped files are packages-internal/api-docs-builder/src/utils/replaceUrl.test.js, packages-internal/core-docs/src/DocsApp/VersionsContext.js, packages-internal/core-docs/src/findActivePage/findActivePage.test.js, packages-internal/core-docs/src/helpers/helpers.test.js, packages-internal/core-docs/src/utils/getProductInfoFromUrl.test.js, packages-internal/markdown/apiPageTranslationLoader.mjs (+1342 more). 1 production file(s) opt out entirely with @ts-nocheck · 30 @ts-ignore suppression(s); the opted-out files are packages/mui-stylis-plugin-rtl/src/index.ts.

What to do

• Migrate the remaining .js/.jsx files to TypeScript.

React / JS · Code Health — Near-exact copy-pasted blocks of substantial extent across the frontend (the D4 clone algorithm over JS/TS tokens, D-386): a block is reported only where its copies still agree on most of their own identifiers and literals, or were renamed as they were pasted but kept most of their constants, and where the copies carry enough code to stand on their own or the copied extent reaches 30 lines — so a re-implementation sharing neither names nor values, and a small pasted declaration, are both found and deliberately not reported, and a clean R10 is not a claim that nothing was copied.

Method: Near-exact copy-pasted blocks of substantial extent across the frontend (the D4 clone algorithm run over JS/TS tokens). Masking finds the candidates; a block is reported when its copies still agree on most of their own identifiers and literals, or when a renamed copy still agrees on most of its constants, AND the copies carry enough code to stand on their own — or when the copied extent reaches 30 lines. So a re-implementation sharing neither names nor values, and a small pasted declaration, are deliberately not counted. Deterministic.

• 210 duplicated blocks under packages/mui-material/src/ have copies in at least two of the sibling directories Accordion, AccordionActions, AccordionDetails, AccordionSummary, Alert, AlertTitle (+116 more sibling(s) not listed) — 104 of them are reported below, and 106 are counted here but not reported individually: those copies match on shape but no longer clear R10's bar for an individually reported row — either they kept neither their own names nor their values, or what was copied is too small to stand on its own (it reports near-exact duplication only, and only of substantial extent). What this row states is the concentration, which the detector measured over all 210 and which does not depend on how exactly each block's copies still match. That concentration is one structural fact, not 210 local ones: the siblings replicate behaviour none of them owns, which is the shape of a missing shared module — a common library every sibling imports — rather than 210 separate extractions. Check first whether the siblings are deliberately standalone deliverables (scaffold templates, demo apps that must stay copy-pasteable); where they are, the duplication is the design and the per-block rows are the ones to act on. — packages/mui-material/src/ListItemButton/ListItemButton.js:40

Where they are, no single extracted module collapses them: each module still has to be written, and what recurs is the TEMPLATE. The moves that do collapse a template are to generate these modules from the set they enumerate, or to replace the repeated construction with one factory each site calls with its own values — and where the set is the point, each module pinning one distinct thing, the repetition IS the enumeration and there is nothing to delete. — packages/mui-codemod/src/deprecations/button-classes/button-classes.js:7

What to do

• Act on each finding's own remediation rather than one rule: the move depends on what recurs. Where the copies are executable blocks, give the shared part one home and call it from each site; where they are declarations, a listing, a specialisation already delegating to its base, or one shape repeated per entity, there is no call site and the move is a shared type, a generated set or a factory — sometimes there is nothing to extract.

(×20) — packages-internal/markdown/loader.mjs, scripts/buildLlmsDocs/index.ts, scripts/generateProptypes.ts, …

What to do

• Add tests that import the unreached modules (directly or through their public entry).

React / JS · Readiness — Whether the project wires up test, lint and typecheck — detected from each package.json script's COMMAND (eslint / tsc / vitest / jest / playwright), not just its name, and corroborated against CI-workflow invocations so a tool run only in CI still counts.

Method: package.json scanned for test/lint/typecheck script wiring. Deterministic presence check.

• This repository declares test tooling, and the ✓ above records that declaration — but packages/mui-codemod/src/v5.0.0/adapter-v4.test/no-styles-import.actual.js and 19 other test file(s) in this workspace cannot be loaded at all: it imports a module that names no file in this repository, so the runner throws while collecting it and none of its cases execute. The wiring is present and the suite it points at does not run as written, which is why the tooling tick must not be read as a statement that the tests pass. Fix the unloadable file(s) — each one is reported with its failing import under Test Coverage — then the declared script exercises what it claims to. — packages/mui-codemod/src/v5.0.0/adapter-v4.test/no-styles-import.actual.js

React / JS · Code Health — Files unreachable from every application/tooling/test entry point, and exports nothing imports (module-graph reachability, D-386).

Method: Dead code: files unreachable from every application/tooling/test entry point plus exports nothing imports, via module-graph reachability. Deterministic, exhaustive over the import graph.

• 1 file(s) (~26 LoC) were excluded from dead-code analysis — declare main/module/exports or a conventional entry (src/index.*, an REDACTED script) so reachability can see this package. — test/bundle-size
• 3 file(s) (~1741 LoC) were excluded from dead-code analysis — declare main/module/exports or a conventional entry (src/index.*, an REDACTED script) so reachability can see this package. — test/bundling/scripts
• 1 file(s) (~12 LoC) were excluded from dead-code analysis — declare main/module/exports or a conventional entry (src/index.*, an REDACTED script) so reachability can see this package. — test/moduleResolution
• Unreachable from the 497 application, 368 tooling and 3162 test entry point(s) detected in this repo. Gate removals on `pnpm run build` — an undetected custom entry would make these reachable.
• no import path from any entry point (497 application, 368 tooling, 3162 test roots considered), and no other file in the scanned tree imports it — nothing in-repo names this module at all, which is the strongest form of this claim the import graph can make (×19) — netlify/functions/feedback-management.mts, netlify/functions/on-deploy.mts, packages-internal/core-docs/src/AppLayout/components/ArrowButton.tsx, …

What to do

• Delete the dead files and unused exports — every line is maintenance cost and rebuild-estimate inflation with zero runtime value.

React / JS · Readiness — npm dependency truthfulness (D-386): unused dependencies, imports not declared anywhere, and type-/test-only packages shipped as production deps.

Method: npm dependency truthfulness: unused dependencies, imports declared nowhere, and type-/test-only packages shipped as production deps — from the manifest + import graph. Deterministic.

• Imported only as a TYPE and declared in no reachable package.json. The import is erased at compile time, so nothing is installed and no runtime resolution depends on it — but type-checking a clean clone will fail. Declare the typings it resolves through (or the package itself) in the owning package.json. (×2) — packages-internal/markdown/loader.mjs:117, packages/mui-codemod/src/util/appendAttribute.js:3
• Imported but not declared in any reachable package.json — installs work only by hoisting accident. (×9) — packages/mui-codemod/src/v5.0.0/theme-spacing.test/large-actual.js:8, packages/mui-codemod/src/v5.0.0/emotion-prepend-cache.test/custom-naming.actual.js:1, packages/mui-codemod/src/v5.0.0/jss-to-styled.test/Anonymous.actual.js:2, …
• Declared in the root package.json but never imported anywhere in that package or its workspace members — no static import reaches it. Usually that is dead weight and attack surface, but two shapes are indistinguishable from source and are NOT dead: an optional or native peer that another dependency loads dynamically at runtime, and a package a build, docs or test step installs and invokes separately. Confirm which of the three this is before removing it. (×3)
• Every import is type-only — move it to devDependencies. — packages/mui-styled-engine/src/index.ts:9

What to do

• Remove unused dependencies, declare unlisted imports explicitly, and demote type-/test-only packages to devDependencies.

React / JS · Architecture — Import cycles in the module graph (D-386) — files that can only be understood and changed together.

Method: Import cycles in the module graph, detected exhaustively over JS/TS imports (the same cycle detection as the .NET coupling dimension). Deterministic.

• packages-internal/api-docs-builder/src/ApiBuilders/ComponentApiBuilder.ts → packages-internal/api-docs-builder/src/buildApi.ts → packages-internal/api-docs-builder/src/ApiBuilders/ComponentApiBuilder.ts (one verified cycle inside a mutually-dependent group of 6 files) — packages-internal/api-docs-builder/src/ApiBuilders/ComponentApiBuilder.ts
• packages-internal/core-docs/src/HighlightedCode/index.ts → packages-internal/core-docs/src/HighlightedCodeWithTabs/HighlightedCodeWithTabs.tsx → packages-internal/core-docs/src/HighlightedCode/index.ts — packages-internal/core-docs/src/HighlightedCode/index.ts

What to do

• Break each cycle by extracting the shared piece into a module both sides can import.
